19×0.09 0.92×0.1简便运算？

Answer 1

脱式计算19×0.09+0.92×0.1
解题思路:四则运算规则(按顺序计算,先算乘除后算加减,有括号先算括号,有乘方先算乘方)即脱式运算(递等式计算)需在该原则前提下进行
解题过程:
19×0.09+0.92×0.1

=（19+1）×0.09+（0.92×0.1-0.09）

=20×0.09+0.002

=1.8+0.002

=1.802

扩展资料~竖式计算-计算过程:先将两乘数末位对齐,然后分别使用第二个乘数,由末位起对每一位数依次乘上一个乘数,最后将所计算结果累加即为乘积,如果乘数为小数可先将其扩大相应的倍数,最后乘积在缩小相应的倍数；
解题过程:
步骤一:9×20=180

根据以上计算步骤组合结果为1.8

Answer 2

19×0.09
=（20-1）×0.09
=20×0.09-0.09
=10×2×0.09-0.09
=2×10×0.09-0.09
=2×0.9-0.09
=1.8-0.09
=1.71
0.92×0.1
=0.92×1÷10
=0.92÷10
=0.092

Answer 3

19×0.09 0.92×0.1简便运算？
解：19×0.09+0.92×0.1
=20×0.09-1×0.09+0.92×0.1
=1.8−0.09+0.092
=1.8-0.09+0.09+0.002
=1.8+0.002
=1.802

Answer 4

算式19×0.092+0.92×0.1的简便解答，具体的步骤如下：
19×0.092+0.92×0.1
=1.9×0.92+0.92×0.1
=（1.9+0.1）×0.92
=2×0.92
=1.84

Answer 5

19×0.09+0.92×0.1
=20×0.09-1×0.09+0.92×0.1
=1.8−0.09+0.092
=1.8-0.09+0.09+0.002
=1.8+0.002
=1.802
